I've been thinking of getting my first proper IEM (split between the Salnotes Zero, QKZ x HBB, Tangzu Wan'er, and CCA CRA+), and I wanted to know if it's better to have IEMs solely for at-home use or if they're durable enough for frequent outdoor use like going to school with them or going on a longer walk. Any response from someone who knows more about IEMs than me (aka anybody) would be appreciated!!
